INTRODUCTION 

NOTE 

This meter has been designed and tested according to 
IEC Publication 348, Safety Requirements for Elec- 
tronic Measuring Apparatus. This manual contains 
information and warnings which must be followed 
to ensure safe operation and retain the meter in safe 
condition. 

WARNING 

READ "MULTIMETER SAFETY" BEFORE 
USING THE METER. 



The Fluke 87 True RMS Multimeter (also referred to as "the 
meter") is a handheld, 4000-count instrument that is designed 
for use in the field, laboratory, and at home. The meter com- 
bines the precision of a digital meter with the speed and versa- 
tility of a high resolution analog display. Frequencies between 
0.5 Hz and 200 kHz can be measured with up to 0.01 Hz resolu- 
tion. The meter is powered by a 9V battery and has a rugged 
case sealed against dirt, dust and moisture. A snap-on holster, 
with flexible stand (Flex-Stand™), protects the meter from 
rough handling. The flexible stand allows the meterto be stood 
or hung. 



The meter also provides: 

• A MIN MAX Recording mode, in which the meter 
"remembers" the lowest and highest readings, calcu- 
lates the true average of all readings taken over a 
period as long as thirty-six hours, and displays these 
values. The beeper emits a Min Max Alert™ when a 
new minimum or maximum reading is recorded. 

• A Peak MIN MAX mode that captures changes as short 
as 1 millisecond. 

• An alternate Frequency Counter mode that measures 
duty cycle and displays it as a value between 0.0 and 
99.9%. 

• An Input Alert™ that causes the beeper to sound if the 
test leads are plugged into the wrong input terminals for 
the function being performed. 

• A REL mode that allows you to store a reading in 
memory, and display the difference between the stored 
value and subsequent readings. 

• A Touch Hold® mode that allows you to keep your eyes 
fixed on the probes when taking measurements in diffi- 
cult or hazardous circumstances, then read the display 
when it is convenient and safe.

• A display back-light that makes the meter useable in 
dark areas. 

• A 4 1 /2-digit display mode for ten times increase in 
resolution. 

• A Capacitance mode that measures capacitors from 
0.01 nFto5//F. 

After unpacking the meter, if you notice that the meter is dam- 
aged or something is missing, contact the place of purchase 
immediately. Save the shipping container and packing mate- 
rial in case you have to reship the meter. 

MULTIMETER SAFETY 

Before usings the meter, read the following safety information 
carefully. Inthis manualtheword, "WARNING," is reserved for 
conditions and actions that pose hazard(s) to the user; the 
word, "CAUTION," is reserved for conditions and actions that 
may damage your meter. The symbols shown in Figure 1 are 
used internationally to denote the electrical functions and 
conditions indicated. If the meter is not used as described in 
this manual, the safety features of the meter might be impaired. 

• Avoid working alone. 

• Do not allow the meter to be used if it is damaged, or its 
safety is impaired.

Inspect the test leads for damaged insulation or exposed 
metal. Check test lead continuity. Damaged leads should 
be replaced. 

Be sure the meter is in good operating condition. During 
a continuity test, a meter reading that goes from over- 
load (OL) to generally means the meter is working 
properly. 

Select the proper function and range for your 
measurement

• Disconnect the live test lead before disconnecting the 
common test lead. 

• Follow all safety procedures for equipment being tested. 
Disconnect the input power and discharge all high- 
voltage capacitors through a protective impedance 
before testing in the O and -w- functions. 

• When making a current measurement turn the power 
off before connecting the meter in the circuit. 

• Check meter fuses before measuring current trans- 
former secondary or motor winding current (See "Fuse 
Test" in the "MAINTENANCE" Section.) An open fuse 
may allow high voltage build-up, which is potentially 
hazardous. 

GETTING STARTED QUICKLY 

Examine the meter carefully, familiarizing yourself with the 
layout of the input terminals, rotary switch, pushbuttons and 
display. Notice the WARNING information and summary of 
power-on options engraved into the rear panel. 

If you have used a multimeter before, simply examining your 
meter will probably give you a good idea how to use it. The 
following procedure is an overview of how to take basic 
measurements. 



GETTING STARTED QUICKLY 



WARNING 

TO AVOID ELECTRICAL SHOCK OR DAMAGE 
TO THE METER, DO NOT APPLY MORE THAN 
1000V BETWEEN ANY TERMINAL AND EARTH 
GROUND. 



1. Insert the test leads in the appropriate input terminals 
(see Table 1 ). If the test leads are in the wrong input ter- 
minals when the meter is turned on and the beeper has 
not been disabled, the beeper will emit a warning. See 
"Input Terminals and Input Alert", below. 



2. To turn the meter on and select a function, turn the rotary 
switch from OFF to the appropriate switch position. All 
segments on the liquid -crystal display (LCD) will turn on 
for one second, then the meter is ready for normal oper- 
ation. If you would like to freeze the display with all seg- 
ments on, press and hold down any button, while turning 
the meter on. As long as the button is held down, all LCD 
segments will remain on. 



3. To select an additional operation, press the appropriate 
pushbuttons above the rotary switch as described in the 
items below. (See also, Figure 2.) 



3 



HOW TO USE THE METER 



• To operate the MIN MAX and RANGE buttons: press to 
select, press again to scroll or increment, and press and 
hold for two seconds to exit. 

• To operate the Hz button: press to select the frequency 
mode, press again to select duty cycle, and press again 
to exit. 

• To operate the back-lit display, press the YELLOW but- 
ton. The back-light automatically turns off in 68 seconds 
to conserve battery life. 

• To operate the remaining buttons: press to select and 
press again to exit. 

NOTE 

The response of the display and the pushbuttons 
slows down in the capacitance mode. 

An annunciator is displayed when a mode has been selected. 
A quick way to reset all the pushbuttons to their default state is 
to turn the rotary switch to an adjacent function and then back 
to the function you are using. 

4. To take a measurement, use the test lead probes to make 
the proper contacts. Remember, insert the meter in the 
circuit in parallel for voltage and in series for current 



4 



measurements. Read the measurement on the display. If 
you did not manually select a range (by using the 
RANGE button), the rangethat provides the best resolu- 
tion is automatically selected. 

5. To run a performance check of the meter, turn the 
rotary switch to Q arid connect a test lead from the 
VO-w-input to the mA //A input. (If you are using a test 
probe, touch the half of the input contact nearest the 
LCD.) The display should read 1 .000 kQ ± 5 digits. With 
the rotary switch still at Q, test the A fuse (15A) by 
inserting the plug end of the test lead into the A input 
and test the mA //A fuse (1 A) by inserting the plug end 
of the test lead into the mA fjA input. The beeper emits 
an Input Alert if the fuses are good. 

Although this procedure will allow you to get started quickly, 
we suggest that you take the time to read the remainder of this 
manual so that you can learn to take full advantage of your 
meter's capabilities.

HOW TO USE THE METER 

Input Terminals and Function Selector Rotary Switch 



Input Terminals and Input Alert 

Items 1-4 describe the input terminals. (See Table 1 for 
overload limits.) If the test leads are connected to the 
Amperes input terminal, and the function selector switch is 
not in the Amp measurement position, the beeper will emit an 
Input Alert. An Input Alert will also sound if the test leads are 
connected to the mAyuA terminal and the function switch is 
not in either Amp position. After an Input Alert sounds, the 
meter will attempt to take a reading from inputs applied to the 
VQ-H- terminal. Input Alert can be disabled by pressing 
( "Hi ) while turning the rotary switch from OFF to any 
function position.

Pushbuttons 

Items 6-13 describe how to use the pushbuttons. These but- 
tons are used (in conjunction with rotary switch) to select 
operating modes and set power-on options. When a button is 
pushed the beeper sounds (unless the beeper has been 
turned off or the Data Output mode has been selected). A 
summary of pushbutton operations is shown in Figure 2. An 
annunciator is displayed to indicate that a mode or option has 
been selected. A quick way to reset all the pushbuttonsto their 
default state is to turn the rotary switch to an adjacent function 
and then back to the function you are using. 

(?) Q Display Back-Light 

Press the YELLOW button to turn on the back-light. 
Back-light turns off automatically after 68 seconds 
to extend battery life.

readings. The MIN, MAX, or AVG annunciator 
turns on to indicate what value is being displayed. 
If an overload is recorded, the averaging function 
is stopped and the average value becomes OL 
(overload). 

The true average of all the readings taken over at 
least a thirty-six hour period can be displayed. If 
this duration is exceeded, the actual minimum and 
maximum readings will continue to be captured 
and can be displayed. However, new averages are 
no longer calculated. The last average calculated 
is retained as the average reading. 

At normal (default) record speed, changes to the 
voltage, current, or resistance inputs that last at 
least 100 milliseconds are recorded, and the "100 
ms" an nunciatorturns on. Press and hold down the

again to return to the maximum (MAX ) read ing. To 
reset the Peak MIN MAX mode press (~^iT) twice: 
the first press exits the mode, and the second press 
re-enters the mod e. To completely exit the MIN 
MAX mode, press (WW) for one second. In Peak 
MIN MAX mode, the present reading, average 
(AVG) readings, and analog display are not dis- 
played. Before selecting Peak MIN MAX, select DC 
voltage or current to DC couple the input waveform; 
or AC voltage to capacitively couple the input wave- 
form. Peak MIN MAX works in all functions except 
ohms, frequency and capacitance. 

In the MIN MAX Recording mode, press to 
stop the recording of readings; press again to res- 
tart recording. If recording is stopped, the minimum, 
maximum, average, and present values are frozen, 
but the analog display continues to be active. When 
recording is stopped, the stored readings are not 
erased and you can still scroll through these 
readings. 

Power-On Option: Select High Accuracy MIN MAX Recording 

The High Accuracy MIN MAX Recording mode has a response 
time of approximately 1 second. Changes of more than 1 second 
duration are recorded. The "1s" annunciator is turned on. In the 
Frequency Counter mode, readings are always recorded at the 
high accuracy recording speed; the response time is not selectable.

Digital and Analog Displays 



(15) iiiililifiltiiitliiliMllllliiil Analog Display 



The analog display is a 32-segment pointer that 
updates at a 40 times per second rate and is the 
best display to use for readings that are changing. 
It does not operate in the Capacitance or Fre- 
quency Counter functions or in the Peak MIN MAX 
mode. 

For increased sensitivity, the analog pointer moves 
across the scale four times for each range. The 
pointer returns to (wraps around) when the 
equivalent digital display reaches 1024, 2048, and 
3072 counts. Select the next higher range if the 
pointer is too sensitive.

Holster and Flex-Stand 



The meter comes with a snap-on holster that absorbs shocks 
and protects the meter from rough handling. The holster is 
equipped with a Flex-Stand. Some uses of the holster with 
Flex-Stand are shown in Figure 3. 

APPLICATIONS 

This section discusses some common applications for your 
meter, and alerts you to some considerations to keep in mind 
when taking measurements. 

Measuring Voltage (AC/DC) 

To measure voltage, connect the meter in parallel with the load 
or circuit under test. Each of the five ac/dc voltage ranges 
presents an input impedance of approximately 10 Mfi in paral- 
lel with less than 100 p F.Ac voltage isac-coupled to the 10 Mfi 
input. 

To improve the accuracy of dc voltage measurements made in 
the presence of ac voltages, measure the ac voltage first. Note 
the ac voltage range and manually select a dc voltage range 
that is the same or higher than the ac voltage range. This 
method improves the dc voltage accuracy by ensuring that the 



APPLICATIONS 
Measuring Voltage (AC/ DC) 



input protection circuits are not being activated. A typical 
application is measuring the dc offset voltage of an amplifier in 
the presence of an ac signal. 

Measurement errors due to circuit loading can result when 
making either ac or dc voltage measurements on circuits with 
high source impedance. In most cases, the error is negligible 
(0.1% or less) if the measurement circuit source impedance is 
10 kilohms or less. 

Measuring Current 

WARNING 

DO NOT ATTEMPT AN IN-CIRCUIT CURRENT 
MEASUREMENT WHERE THE POTENTIAL IS 
GREATER THAN 600V. YOU MAY DAMAGE THE 
METER OR BE INJURED IF THE FUSE BLOWS 
WHILE CURRENT IS BEING MEASURED IN A 
CIRCUIT WHICH EXHIBITS AN OPEN CIRCUIT 
VOLTAGE GREATER THAN 600V. 

To measure current, connect the meter in series with the load 
or circuit under test. Press the BLUE button to toggle between 
alternating and direct current.

If you do not know approximately what the current is, connect 
the circuit to the A inputterminalfirsttoseeifyouhaveasafe 
level for the mA/jA input terminal. Use the mAM input 
terminal for current up to 400 mA. 

When measuring current, the meter's internal shunt resistors 
develop a voltage across the meter's terminals called "burden 
voltage." This voltage drop is very low in your meter, but it may 
affect precision circuits or measurements. 

To calculate the burden voltage: in A, multiply the display 
reading by 0.03V; in mA, multiply the display reading by 1.5 mV; 
\r\fiA, multiply the display reading by "IOOaiV. For example, at a 
20 mA display reading, the burden voltage is 20.00 x 1.5 mV = 
30 mV. 

The approximate resistance between the input terminals is 
0.03 ohms for A, 1.5 ohms for mA, and 100 ohms for/yA. 



Continuity Testing 

Continuity testing verifies that circuit connections are intact. 
To perform audibl e con tinuity tests, set the rotary switch to 
mil n press the ( -mi ) button, and connect the meter to your 
circuit. Test resistances below the values listed in Table 2 
cause the meter to emit a continuous tone. Use the 400 ohm 
range for most wiring checks. 



APPLICATIONS 
Measuring Current 



The continuity mode is extremely fast and can be used to 
detect either shorts or opens that last for as little as 1 milli- 
second. When a change is detected, the beeper tone is 
"stretched" to last at least V* second so you can hear it and 
detect both shorts and opens. This can be a valuable trouble- 
shooting aid when looking for intermittents associated with 
cables, connections, switches, relays, etc. If the test value is 
very close to the th reshol d , erratic beeps ca n a Iso occur d ue to 
environmental electrical noise (EMI). 

Measuring Resistance 

CAUTION 

Turn off power on the test circuit and discharge 
all capacitors before attempting in-circuit resist- 
ance measurements. If an external voltage is 
present across a component, it will be impossible 
to take an accurate measurement of the resist- 
ance of that component. 

The meter measures resistance by passing a known current 
through the external circuit or component, measuring the vol- 
tage drop, and calculating the resistance using Ohm's Law 
(0=V/A). Remember, the resistance displayed by the meter is 
the total resistance through all possible paths between the 
probes. This explains why in-circuit measurement of resistors 
does not often yield the ohms value indicated by the resistor's 
color code. 



19 



APPLICATIONS 
Measuring Resistance 



The resistance in the test leads can diminish accuracy on the 
lowest (400-ohm) range. The error is usually 0.1 to 0.2 ohms for 
a standard pair of test leads. To determine the error, short the 
test leads together and read the resistance of the leads. Use 
the Relative (REL) mode to automatically subtract the lead 
resistance from resistance measurements. 

When measuring resistance, be sure that the contact between 
the probes and the circuit under test is good. Dirt, oil, solder 
flux, or other foreign matter seriously affect resistance. 

Most in-circuit resistance measurements can be made with- 
out removing diodes and transistors from the circuit The full- 
scale measurement voltage produced on ranges below 40 MO 
does not forward-bias silicon diodes or transistor junctions 
enough to cause them to conduct. Use the highest range you 
can (except 40 MO) to minimize the possibility of turning on 
diodes ortransistor junctions. Full-scale measurement voltage 
in the 40-MQ range does forward-bias a diode or transistor 
enough to cause it to conduct. 

In resistance (and all other functions except current), the 
mA (iA input is connected to a 1-kilohm resistor. If the 
mA jjA input protection fuse is good, this input can be used 
as a partial check of proper operation in resistance. The input 



20 



receptacles have split contacts; touch the probe to the half 
nearest the LCD. The 1-kilohm resistor is protected by a 
3-diode clamp. Do not apply external voltage; it may blow the 
fuse. 

Using Conductance for High Resistance or Leakage Tests 

Conductance is the inverse of resistance (i.e., 1 /ohms) and is 
measured in units of nanosiemens (nS = 1 x 10 9 Siemens). The 
40-nS range on your meter effectively extends the resistance 
measurement capability to 100,000 MO. The 40-nS range can, 
therefore, be used to test the resistance or leakage in insula- 
tors, diodes, transistors, cables, connectors, printed circuit 
boards, transformers, motors, capacitors, or other high resist- 
ance components. 

To me asure conductance, set the rotary switch to milO-fr-, and 
press (range) to manually increment to the 40-nS range. Plug 
the test leads into the VO-h- and COM input terminals, and 
then connect these leads across the unit under test. The read- 
ing displayed is in units of conductance (nS). To convert this 
reading to megohms, divide the reading into 1000 (1000/dis- 
played reading in nS = MO). For example 2.00 nS converts to 
500 MO (1000/2.00). High value resistance measurements are 
susceptible to induced noise and may require careful shield- 
ing. To smooth out most noisy readings, enter the MIN MAX 
Recording mode and scroll to the average (AVG) reading. 



NOTE 



In the conductance range, there is normally a small 
residual reading with open test leads. To ensure 
accurate measurements, connect clean test leads to 
the meter and (with the leads open) read the 
residual leakage in nanosiemens. Correct subse- 
quent measurements by using the Relative mode 
(REL) to 2ero the display, which subtracts the 
residual from the readings. 

Diode leakage tests require that the diode junction be reverse- 
biased when being measured. To do this, connect the anode of 
the diode to the COM input terminal and the cathode (ring) of 
thediodetothe VQ-»+- input terminal. Leakage at the test volt- 
age being applied can then be read in terms of conductance. 

High-voltage, stacked diode, assemblies can usually be tested 
for forward and reverse resistance changes using conduc- 
tance. These assemblies typically have such high forward volt- 
age drops that the diode test or resistance modes cannot test 
them. 

Noisy Resistance Measurements 

Your Fluke meter is designed to tolerate up to several volts of 
ac noise. Noise appears as changing numbers on the digital 
display and as an oscillating analog display. Changing the 



APPLICATIONS 
Measuring Capacitance 



range may reduce the noise. To smooth out the effect of noise 
on your readings, enter the MIN MAX Recording mode and 
scroll to the average reading. 

Measuring Capacitance 

CAUTION 

Turn off power and discharge the capacitor 
before attempting a capacitance measurement. 
Use the ( V ) function to confirm that the capaci- 
tor is discharged. 

The meter measures capacitance by charging the capacitor 
with a known current, measuring the resultant voltage, and 
calculating the capacitance. The measurement takes about 1 
second per range (push button responses also take about 1 
second). The capacitor charge can be up to 1.2V. 

For measuring capacitor values up to 5.8/uF, turn the rotary 
switch to 'Win -it-, press the BLUE button, and connect the 
test leads to the capacitor. The meter will select the proper 
range automatically. Each measurement takes about 1 
second per range. Wh en mak ing repeated measurements of 
similar values, press QwqQ to manually select the proper 
range and to speed up subsequent measurements. For 
capacitors less than 5 nF or in noisy environments, use short 
test leads or a test fixture (1 nF - 1000 pF). 



21 



APPLICATIONS 
Diode Testing 



The measurement accuracy of capacitors less than 5 nF can 
be improved by first using the Relative mode to zero the dis- 
play and automatically subtract the residual meter and test 
lead capacitance. Since the Relative mode also selects man- 
ual ranging, zero the residual capacitance only when measur- 
ing small value capacitors. 

Residual voltage charges on the capacitor, or capacitors with 
poor insulation resistance or poor dielectric absorption may 
cause measurement errors. 

To check capacitors larger than 5^, select fl with the rotary 
switch (or press the BLUE button if you are in the capacitance 
mode). Select an appropriate range from Table 4. Discharge 
the capacitor, connect the capacitor to the meter, and time the 
number of seconds it takes for the charge to go from zero to full 
scale. At full scale, all of the analog display segments are on. 
To estimate the value of the capacitor, multiply the number of 
seconds times the charge rate (j/F/sec) in Table 4. For exam- 
ple, a 10//F capacitor takes about 33 seconds to charge in the 
4 MQ range or 3.3 seconds in the 400 kd range. To reconfirm 
your estimate, reverse the test leads; when the capacitor 
discharges to zero (the analog display polarity switches from 
- to +), start timing the recharge to full scale. 



22 



Diode Testing 

To perform a diode or transistor junction test plug the test 
leads into the Vf}-«- and COM inputs, turn the rotary switch to 
-*»-, and connect the test leads across the diode(s). 

In diode test, voltage is developed across the component(s) by 
a test current (approximately 1 mA with the test leads shorted) 
from the meter. Voltage is read on a single to +3.000V range 
that can measure up to five silicon diode or transistor junctions 
in series. For a silicon diode, the typical forward voltage should 
be about 0.6V. Voltages greater than 3.00V or open test leads 
produce an overload (OL) reading. If the digital reading is the 
same in both directions, the diode junction is probably shorted. 
If the display reads OL in both directions, the diode junction is 
probably open. To protect sensitive devices, the open test lead 
voltage from the meter will not exceed 3.9V. Negative inputs 
(from an external power source, for example) are not 
suppressed.

Use the Touch Hold mode (see item 10) to make audible diode 
tests. When the test leads are placed across the diode, a good 
diode or transistor junction will cause the meter to beep (and 
update the display) in the forward-biased direction and remain 
silent in the reverse- biased direction. A short or resistance 
below about 4000 ohms will causea beep in both directions. If 
an open is detected, the meter will remain silent in both 
directions. 

Using the Analog Display 

The analog display is easy to use and interpret It functions 
much the same as the needle on an analog meter without the 
mechanical overshoot inherent in needle movements. 

The analog display is especially useful for peaking and nulling, 
and observing rapidly changing inputs. The analog display 
response time is fast, and it can be used to make approximate 
adjustments quickly. The 4000-count digital display can then 
be used for final adjustment. 

The analog display can also be used for limited diagnostic 
purposes. In situations where rapidly fluctuating signal levels 
make the digital display useless, the analog display is ideal. 
Like the needle on a Volt-ohm-milliammeter (VOM), the analog 
display excels at displaying trends, or slowly changing signals. 
Many diagnostic routines using the analog display require 
practice. You will usually be looking for good or bad signal 



APPLICATIONS 
Using the MIN MAX Recording Mode 



patterns that occur over some span of time. Noisy resistance 
measurements, for instance, create such patterns. Therefore, 
familiarity with analog display response and movement is 
necessary to accurately interpret a signal pattern. Compare 
the analog display response when making measurements on 
a unit known to be good, to the analog display response when 
making measurements on a faulty unit 

Using the MIN MAX Recording Mode 

The MIN MAX Recording mode can be used to catch inter- 
mittents and turn on or turn off surges, verify performance, 
measure while you are away ("baby sit"), or take readings 
while you are operating the equipment under test and cannot 
watch the meter. The audible Min Max Alert indicates when a 
new minimum or maximum value has been recorded. 

You can select either a 100 millisecond, 1 millisecond (Peak), 
or 1 second (high accuracy) "response time" for recording 
minimum and maximum readings. The response time is the 
length of time an input must stay at a new value to record the 
full change. 

The 100 millisecond response time is best for recording power 
supply surges, inrush currents, and finding intermittent fail- 
ures. This mode follows the update time of the analog display. 
(The minimum and maximum excursions of the analog display 
get recorded.) 



23 



APPLICATIONS 
Measuring Frequency 



The 1 millisecond Peak MIN MAX mode is ideal for recording 
transients, especially from intermittant power lines orconnec- 
tions. This mode can also be used to measure the + and - peak 
values of sinewaves up to about 450 Hz, for easy measurement 
of both peak line voltage and line current measurements of 
power supplies and electrical equipment. 

The high accuracy mode (1 second response time) follows the 
digital dis play a nd can be selected as a power-on option by 
pressing (umuax ) while turning the meter on. This mode has 
the full accuracy of the meter and is best for recording power 
supply drift, line (mains) voltage changes, or circuit perfor- 
mance while line voltage, temperature, load, or some other 
parameter is being changed. Frequency Counter readings are 
recorded only in the high accuracy mode. 



In the MIN MAX Recording mode, the true average of all read- 
ings taken since entering MIN MAX is calculated. The average 
value displayed in both the 100 millisecond and 1 second 
modes is the mathematical integral of the input (within the 
response time and accuracy specifications of the meter). 
When you display the average, the reading rate slows some- 
what in order to calculate the average of the accumulated 
readings. 



24 



The average reading is useful for smoothing out unstable or 
changing inputs, calculating power consumption (such as 
kilowatt hours), estimating the percent of time a circuit is oper- 
ational, or verifying circuit performance (or temperature with 
the optional 80TK Thermocouple Module). 

If you want to record readings only during the duration of a 
particular test (such as during the frequency response sweep 
of an audio amplifier, for example), apply the input signal, start 
the test (or sweep , in this exa mple), and let the meter stabilize. 
Now press (mw *w) ,then press (Hotos>) ,and stop the testThe min- 
imum, maximum, and average of all readings ta ken du ring the 
test are now held in memory. Momentarily press (*w»Mx) to scroll 
to the reading of interest. Be careful: if you hold down the O**""**) 
for longer than a second, you will exit the MIN MAX Recording 
mode and erase the memory. As long as the rotary switch is not 
turned and the other pushbuttons (except REL) are not 
pressed, these readings will remain in memory until the battery 
dies. 

Measuring Frequency 

In the Frequency Counter mode, the frequency display auto- 
ranges to one of five ranges: 199.99 Hz, 1999.9 Hz, 19.999 kHz, 
199.99 kHz, and greater that 200 kHz. For frequencies below 



10 Hz, the update rate slows and follows the input signal. For 
frequencies between 0.5 Hz and 0.3 Hz, the display may not 
be stable. For frequencies below 0.3 Hz, the display shows 
0.000 Hz. 

For most frequency measurements, turn the rotary switch to 
theVsetting, co nnect t he meterto the signal being measured, 
and then press C~*~) button. Connecting the meter to the 
signal before pressing Hz will normally allow the meter to 
autorange to an appropriate range, but the minimum input 
signal required to trigger the frequency counter varies, 
depending on the range and frequency (see Specifications). 
If the input signal is below the trigger level, frequency 
measurements will not be taken. If your readings are 
unstable, the input signal may be near the trigger level for 
that range. You can usually correct this by selecting a lower 
range. In the Frequency Counter mode, the range (displayed 
in the lower-ri ght co rner of the LCD) will only change when 
you press the (/mngF) button. 

If your readings seem to be a multiple of what you expected, 
your input signal may have distortion or ringing. (For 
example, electronic motor controls distort both voltage and 
current waveforms.) Select a higher input range if you 
suspect multiple triggering. An alternative is to turn the rotary 
switch to the'v or m"v setting, which will shift the trigger level 
from 0V to a positive voltage that changes with each range. In 
general, the lowest frequency displayed is the correct one. 



APPLICATIONS 
Measuring Frequency 



In the Frequency Counter mode, the input range acts like an 
attenuator, the V function ac-couples the input signal, and 
the V and m'v functions dc-couple the input signal. The V 
function is optimized for triggering on logic and switching 
signals. The 4V dc range is optimized to trigger on all 
common 5V logic families (triggers at 1.7V ± 0.1V). High 
frequency logic signals may require the use of the 400 mV ac 
range. The 40V dc range is optimized to trigger on automotive 
switching signals (triggers at 4V ±1V). All ranges in the V 
function trigger at approximately 10% of range, exceptforthe 
4V range. 

Frequency measurements can be made on current inputs. The 
inputs are always dc-coupled. The triggering characteristics 
are shown in Table 5.

APPLICATIONS 
Measuring Duty Cycle 



Measuring Duty Cycle 

Duty Cycle (or duty factor) is an alternate Frequency Counter 
mode that displays, in percent, the time the input signal is 
above the trigger level (or below the trigger level if the negative 
trigger slope is selected). The Duty Cycle mode is optimized for 
measuring the on or off time of logic or switching controls. 
Many industrial control systems (electronic fuel injection in 
automobiles, for example) are pulse-width modulated, and 
duty cycle measurements provide a quick check on their 
performance. 

For logic level signals, use the 4V dc range. For 1 2V switching 
signals in automobiles, use the 40V dc range. For sine waves, 



use the most sensitive range you can without getting double 
triggering. (Normally, a clean signal can be up to ten times the 
amplitude of the range you are on.) Duty cycle measurements 
can also be used as an indication of potential triggering prob- 
lems on sine wave or near sine wave signals. If you do not 
measure approximately 50% duty cycle, you may have a dis- 
torted waveform. 

In Duty Cycle (and Frequency Counter) mode, the slope (or 
edge) on which the counter triggers is selected by pressing 
C "ii ) . The slope selected is indicated by a + or - annunciator 
in the lower-left corner of the LCD. The waveform shown in 
Figure 4 represents the duty cycle measurement of a typical 
logic signal.

Figure 4. Duty Cycle Measurement of Typical Logic Signal 



The manner in which your meter takes duty cycle measure- 
ments allows it to be very tolerant of aperiodic (repetitive but 
not periodic) signals. Duty cycle measurements on low fre- 
quency (<400 kHz) aperiodic logic signals, especially serial 
communication signals, is a simple form of signature analysis. 
A known pattern will read the same duty cycle every time (if the 
pattern repeats in less than 1 /3 second). 

The precision and resolution of the duty cycle measure- 
ments are achieved by averaging many repetitions of the 
input signal. In rare cases, this averaging technique (which is 
similar to pulse-width averaging in a conventional counter) 
may cause a measurement problem called "aliasing." Alias- 
ing results when the frequency of the input signal happens to 
be exactly synchronized with the reference crystal oscillator 
of the meter. This occurs when the frequency of the input 
signal can be exactly divided into the frequency of the 
oscillator (1 31 ,072 Hz) or one of the oscillator's harmonics. 
When they are nearly synchronized, the meter is "blind" to 
the correct duty cycle, and the display will alternate between 
incorrect readings. If this occurs, and the frequency reading 
was stable, press (Wmax) to select the MIN MAX Record 
mode and scroll to the average display. The average display 
will stabilize on the correct duty cycle. 

A common duty cycle measurement is the "dwell" angle in an 
automobile. Dwell is the number of degrees of distributor rota- 
tion that the points remain closed (or current is flowing in the 



APPLICATIONS 
Pulse Width Measurements 



coil). Use the following to convert a dwell angle to duty cycle (in 
percent): 

% Duty Cycle = DweN (degrees) * No. of Cylinders * 100 

360 degrees 

To make a dwell measure ment, set the rotary switch to V , 
select the 40V range, press ( )twice(the%annunci atoron 
the right side of the LCD should turn on), and press the ( "»» ) 
(to select the negative trigger slope so the measurement will be 
the "off" or points closed time). Then connect the COM input to 
ground, and connect the VO-*+ inputto the low (or switched) 
side of the coil. Most automobiles have the points closed for a 
duty cycle between 50-70%. 



Pulse Width Measurements 

For a periodic waveform (that is, repetitive at equal time 
intervals), a duty cycle measurement can be easily converted 
to pulse width. First measur e the frequency and then 
measure the duty cycle. Toggle r~^iT) to select the polarity of 
the pulse you want to measure. To convert frequency and 
duty cycle measurements into a pulse width, use the

MAINTENANCE 

Repairs or servicing not covered in this manual should only be 
performed by qualified personnel as described in the 80 Series 
Service Manual (P/N 834168). 

General Maintenance 

Periodically wipe the case with a damp cloth and detergent 
(do not use abrasives or solvents). If the input alert is falsely 
activated by moisture: 

1 . Turn the multimeter off and remove all test leads. 

2. Shake out the input receptacles. 

3. Use a clean swab in each of the four terminals to 
dislodge and clean out the contamination. 

4. Soak a new swab with the cleaning and oiling agent 
WD40. Work this swab around in the A and mA //A 
terminals. Since the oiling agent insulates the terminals 
from moisture-related shorting, this preventive treat- 
ment ensures against future erroneous Input Alerts. 

Calibration 

Calibrate your meter once a year to ensure that it performs 
according to its specifications. Contact the nearest Service 



28 



Center or refer to the 80 Series Service Manual for calibration 
procedures. For replacement parts, seethe parts list at the end 
of this manual. 

WARNING 

TO AVOID ELECTRICAL SHOCK, REMOVE THE 
TEST LEADS AND ANY INPUT SIGNALS 
BEFORE REPLACING THE BATTERY OR 
FUSES. TO PREVENT DAMAGE OR INJURY, 
INSTALL ONLY QUICK ACTING FUSES WITH 
THE AMP/VOLT RATINGS SHOWN IN FIGURE 
5. 



Battery Replacement 

The meter is powered by a single 9V battery (NEDA 1604, 6F22, 
or006P). Referring to Figures, use the following procedure to 
replace the battery: 

1. Disconnect test leads from any live source, turn the 
rotary switch to OFF, and remove the test leads from the 
front terminals. 

2. The case bottom is secured to the case top by three 
screws and two internal snaps (at the LCD end). Using a 
Phillips-head screwdriver, remove the three screws 
from the case bottom and turn the case over.

3. Lift the input terminal end of the case top until it gently 
unsnaps from the case bottom at the end nearest the 
LCD. 

4. Lift the battery from the case bottom, and carefully dis- 
connect the battery connector leads. 

5. Snap the battery connector leads to the terminals of a 
new battery and reinsert the battery into the case bot- 
tom. Dress the battery leads so that they will not be 
pinched between the case bottom and case top. 

6. Ensure that the case top rotary switch and circuit board 
switch are in the OFF position. 

7. Replace the case top, ensuring that the gasket is prop- 
erly seated and the two snaps on the case top (at the end 
near the LCD) are engaged. Reinstall the three screws. 

Fuse Test 

Use the following procedure to test the internal fuses of the 
meter. 

1. Turn the rotary selector switch to hid n Ht-. 

2. Plug a test lead into the VQ-w- inputterminal and touch 
theprobetothe A inputterminal. Because the recepta- 



cles of the input terminals contain split contacts, be sure 
that you touch the probe to the half of the receptacle 
contact that is nearest the LCD. 

3. The display should indicate between 00.0 and 00.5 
ohms. This tests F2 (15 A, 600V). If the display reads OL 
(overload), replace the fuse and test again. If the 
display reads any other value, have the meter serviced. 

4. Move the probe from the A input terminal to the 
mAfjA inputterminal. 

5. The display should indicate between 0.995 kilohms 
and 1.005 kilohms. This tests F1 (1A, 600V). If the 
display reads OL (overload), replace the fuse and test 
again. If the display reads any other value, have the 
meter serviced. 

Fuse Replacement 

Referring to Figure 5, use the following procedure to examine 
or replace the meter's fuses: 

1. Perform steps 1 through 3 of the battery replacement 
procedure. 

2. Remove the defective fuse by gently prying one end of 
the fuse loose and sliding the fuse out of the fuse 
bracket. 



30 



3. Install a new fuse of the same size and rating. Make sure 
the new fuse is centered in the fuse holder. 

4. Ensure that the case top rotary switch and circuit board 
switch are in the OFF position. 

5. Replace the case top, ensuring that the gasket is prop- 
erly seated, the battery leads are properly dressed, and 
the two snaps on the case top (at the end near the LCD) 
are engaged. Reinstall the three screws. 

Service 

If the meter fails, check the battery and fuse(s) and replace as 
needed. If the meter still does not work properly, review this 
manual to make sure you are operating it correctly. If the meter 
still malfunctions, pack it securely in its original shipping 
container and forward it, postage paid, to the nearest Service 
Center. Include a description of the malfunction. Fluke 
assumes NO responsibility for damage in transit.

* Accuracy is given as +/-([% of reading] + [number of least significant digits]) at 1 8" C to 28° C, with relative humidity up to 90%, for a period 
of one year after calibration, in the 4 1/2-digit mode, multiply the number of least significant digits (counts) by 10. AC conversions are 
ac-coupled, true rms responding, calibrated to the rms value of a sine wave input, and valid from 5% to 100% of range. AC crest factor 
can be up to 3 at full scale, 6 at half scale. For non-sinusoidal wave forms add -(2% Rdg + 2% Fs) typical, for a crest factor up to 3. 

** Below 10% of range, add 16 counts. 

f The Fluke 87 is a True-RMS responding meter. The meter will display a reading (typically < 25 digits) when the input leads are shorted 
together in the A C functions which is caused by internal amplifier noise. The accuracy of the Fluke 87 is not significantly affected by this 
internal offset when measuring inputs that are within 5% to 100% of the selected range. When the RMS value of the two values (5% of 
range and internal offset) is calculated, the effect is minimal as shown in the following example where 20. 0=5% of 400 mV range, and 
2.5 is the internal offset: 

RMS = SQRT[(20.0) 2 + (2.5) 2 ] = 20. 16 

If you use the REL function to zero the display when using the AC functions, a constant error that is equal to the internal offset will result.
